FREQUENTLY ASKED QUESTIONS

Is the PLASMA Rack stereo?

The PLASMA Rack is a mono 1 U unit. Linking two PLASMA Rack units together via MIDI, it is possible to use as a true stereo device.

Does it have an input on the front panel?

The PLASMA Rack only features inputs and outputs on the back of the device.

Does it have balanced and unbalanced inputs?

It does! It features unbalanced jack input for your instrument, unbalanced XLR/ Jack input for your mic or line signal. And the same for the outputs – one unbalanced output, one balanced output.

Does it have presets?

You can save and recall up to 8 presets by MIDI Programm Change messages – 01 – 08.

Can the PLASMA Rack be controlled with an expression pedal?

As it features an expression pedal input, you can control your chosen parameter via a standard expression pedal.

Does it have midi?

It does! Via MIDI you can recall your favorite presets (using CC messages), control another PLASMA Rack, or control your PLASMA Rack via MIDI controller.

Is the sound actually going through the plasm atubes or is it just blinking from the input signal?

It is the actual discharge path for the high voltage signal! These discharges have an unusual spectrum and they are responsible for that electric crackling sound.

Aren't plasma globes known for causing RF interference? Any chance wthis will cause bleeding in adjacent modules?

The PLASMA Rack doesn’t cause any RF interference. The PLASMA Rack has been tested in a certified laboratory and passed Electro-magnetic compatibility tests. Sensitive devices e.g. guitar pickups can pick up noise in very, very close proximity.

Does the Plasma tube fall under the warranty?

The expected life of the xenon tube is 10,000 to 70,000 hours of active playing. The tube is under warranty. No other colors are available.

Does the PLASMA Rack come with a power supply?

Gamechanger Audio PLASMA Rack comes with a power cable that’s suitable for your region.
